I bought an as new/used phone almost two years ago. Asked DP to put a protector on it whilst I was cooking, knocked it off the side 20 minutes later and there were huge cracks across the screen despite it being in a case as well.
Meh, no point moaning that he didn't get around to it, shit happens, it still worked, no insurance, my problem, not his. Still slightly miffed that it broke, but at least it has still been usable.
I've just taken it out of the case for the first time because I was about to order a new phone and realised MY PHONE IS PERFECT. It was the screen protector that cracked.
I'm a twat.
